Abstract

Le support hydraulique, qui consiste en un cylindre de travail (6) couplé à un système de direction mécanique, en une pompe (19, 36) et en une vanne-pilote (12), ne fonctionne qu'au-delà d'une force de direction prédéterminée. On obtient une direction assistée de fonctionnement fiable et de conception simple grâce au déplacement contre une force de prétension, sous l'effet de la force de direction, d'un élément (2) du système de direction mécanique qui est monté de manière coulissante par rapport au corps du véhicule, ce déplacement servant à l'actionnement mécanique de la vanne-pilote (12).
